In 2005, Dr. Denis Doorly of Imperial College, London, built and tested airflow through a see-through model of the nose. He concluded that "airflow in the nose is not simply laminar or turbulent." Is the fact that our noses produce some turbulent ("disordered") airflow an indication of poor design? Interestingly, the turbulence causes eddies to waft upward, allowing controlled puffs of air into the narrow space above the upper concha where the sensitive olfactory nerves are located. Much of our sense of smell depends on this unique airflow pattern. Most of the air is not wafted up, but jetted down. It is likely that this flow rate is increased by the downward curvature of the conchae, which may utilize the Coanda effect. This effect can be demonstrated by observing how fluid speeds up as it runs down the back of a vertically held spoon.
The same principles utilized by our noses are being considered by engineers in their quest to build more efficient machines. For example, the Boeing 787 Dreamliner is currently in production and promises to operate 20 percent more efficiently than the similarly-sized 767 (a 1982 product). Source [link] Thanks |
